Comprehensive Endovascular and Open Surgical Management of Cerebral Arteriovenous Malformations

Surgery is the gold standard for accessible arteriovenious malformations (AVMs), and pre-operative embolization can simplify this procedure. We describe our approach for staged endovascular embolization and open resection of AVMs, and provide a representative clinical example highlighting the advantages of a comprehensively trained neurovascular surgeon leading a multi-disciplinary clinical...

Open Surgical Resection of Cerebral Arteriovenous Malformations

Source: Rennert, R. C., et al. Comprehensive Endovascular and Open Surgical Management of Cerebral Arteriovenous Malformations. J. Vis. Exp. (2017).This video demonstrates the open surgical resection of a cerebral arteriovenous malformation (AVM) in a human brain. The procedure involves creating a bone flap, accessing the subarachnoid space, identifying and occluding feeding arteries and draining veins, and carefully removing the AVM. Intraoperative angiography confirms complete resection,...

Visual Evoked Potential Recording in a Rat Model of Experimental Optic Nerve Demyelination06:49

Visual Evoked Potential Recording in a Rat Model of Experimental Optic Nerve Demyelination

Focal demyelination is induced in the optic nerve using lysolecithin microinjection. Visual evoked potentials are recorded via skull electrodes implanted over the visual cortex to examine the signal conduction along the visual pathway in vivo. This protocol details the surgical procedures underlying electrode implantation and optic nerve microinjection.

Measuring Spinal Presynaptic Inhibition in Mice By Dorsal Root Potential Recording In Vivo09:48

Measuring Spinal Presynaptic Inhibition in Mice By Dorsal Root Potential Recording In Vivo

GABAergic presynaptic inhibition is a powerful inhibitory mechanism in the spinal cord important for motor and sensory signal integration in spinal cord networks. Underlying primary afferent depolarization can be measured by recording of dorsal root potentials (DRP). Here we demonstrate a method of in vivo recording of DRP in...

A Novel Murine Model of Arteriovenous Fistula Failure: The Surgical Procedure in Detail

Here we present a murine model of arteriovenous fistula (AVF) failure in which a clinically relevant anastomotic configuration is incorporated. This model can be used to study the pathophysiology and to test possible therapeutic...

A Mouse Model of Direct Anastomosis via the Prespinal Route for Crossing Nerve Transfer Surgery

We simulated clinical surgery to establish a protocol of direct anastomosis of bilateral brachial plexus nerves via the prespinal route in mice, contributing to the study of the neural mechanisms underlying rehabilitation upon crossing nerve transfer after central and peripheral nervous system...
